Description

Technical Field

[0001] This utility model relates to the field of logistics automation technology, and in particular to a handling trolley. Background Technology

[0002] Currently, most logistics handling trolleys adopt a swing-open baffle structure, which uses a hinge mechanism to open and close the baffle. This structure needs to complete a cycle of opening, loading, and closing during the handling process to prevent goods from falling off during transportation.

[0003] However, the flipping radius of the baffle requires a relatively large operating space. In dense warehousing environments, when the handling trolley flips the baffle, it is very easy for the baffle to interfere with the shelves, goods, or adjacent equipment. In addition, the hinged baffle structure experiences rapid mechanical wear and has high maintenance costs. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a handling trolley. Compared to handling trolleys with a hinged baffle structure, the chain gate baffle assembly does not need to flip during the opening or closing of the inlet and / or outlet, thus avoiding interference with shelves, goods, or adjacent equipment during the flipping process.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] This utility model provides a transport trolley, comprising:

[0007] The vehicle body;

[0008] A vehicle frame, mounted on the vehicle body, having a feed inlet and / or discharge outlet on its side, and a guide groove assembly located on the side where the feed inlet and / or discharge outlet is located and extending to the top surface of the vehicle frame; and

[0009] The chain gate baffle assembly is slidably connected to the guide groove assembly to open or close the feed port and / or the discharge port.

[0010] In some implementations, the guide groove assembly includes a first guide groove and a second guide groove respectively disposed on opposite sides of the feed inlet and / or the discharge outlet, wherein the first guide groove and the second guide groove are arranged in parallel.

[0011] In this implementation, the two opposite sides of the chain gate baffle assembly are slidably connected to the first guide groove and the second guide groove, respectively, thereby ensuring the stability of the chain gate baffle assembly during the sliding process, avoiding jamming during the sliding process, and making the overall structure more reliable.

[0012] In some implementations, the feed inlet is located on a first side of the vehicle frame, and the discharge outlet is located on a second side of the vehicle frame, with the discharge outlet positioned opposite to the feed inlet.

[0013] In this implementation, when the feed inlet and the discharge outlet are arranged opposite to each other, there are two guide groove assemblies. The two guide groove assemblies are respectively located on the side where the feed inlet and the discharge outlet are located and extend to the top surface of the vehicle frame.

[0014] In some implementations, the chain gate baffle assembly includes a rotating shaft, a sprocket, a chain, and multiple baffles. The two ends of the rotating shaft are rotatably connected to opposite sides of the feed inlet and / or the discharge outlet, respectively. The sprocket is sleeved on the rotating shaft. The chain meshes with the sprocket and is slidably connected to the first guide groove and the second guide groove, respectively. The multiple baffles are sequentially connected to the side of the chain away from the sprocket.

[0015] In some implementations, the chain gate baffle assembly further includes a drive mechanism that is driven to the rotating shaft.

[0016] In this implementation, the drive mechanism drives the rotating shaft to rotate, causing the chain to slide, thereby causing the chain to slide back and forth between the guide groove assembly located on the side where the feed port and / or discharge port are located and the guide groove assembly located on the top surface of the frame body, thereby opening or closing the feed port and / or discharge port.

[0017] In some implementations, the drive mechanism includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a first drive member. The first synchronous pulley is sleeved on the shaft and abuts against the side of the frame away from the sprocket. The second synchronous pulley is rotatably connected to the side of the frame. The first end of the synchronous belt is movably sleeved on the first synchronous pulley, and the second end is movably sleeved on the second synchronous pulley. The first drive member is driven and connected to the second synchronous pulley.

[0018] In some implementations, the vehicle body includes an annular conveyor belt and a second drive member, the annular conveyor belt being movably disposed at the bottom of the vehicle frame body, and the second drive member being drivenly connected to the annular conveyor belt.

[0019] In some implementations, the baffle includes a plate body and a scraper, the scraper being connected to the bottom of the plate body so that when the plate body approaches the annular conveyor belt, the scraper sweeps the annular conveyor belt.

[0020] In this implementation, when the chain gate baffle assembly closes the inlet and / or outlet, the circular conveyor belt of the transport trolley is continuously driven during movement, causing the circular conveyor belt to continuously rub against the scraper. In this way, the scraper can sweep the circular conveyor belt, thereby preventing dust accumulation.

[0021] In some implementations, the top of the plate body is provided with a clearance channel to avoid obstructing the scraper adjacent to the plate body.

[0022] In some implementations, the transport trolley also includes a support frame, which is connected to opposite sides of the bottom side of the trolley frame. The support frame is located inside the annular conveyor belt and its top surface abuts against the bottom surface of the annular conveyor belt.

[0023] The transport trolley provided by this utility model has a guide groove assembly located on the side where the inlet and / or outlet are located and extending to the top surface of the frame. The chain gate baffle assembly is slidably connected to the guide groove assembly. The chain gate baffle assembly opens or closes the inlet and / or outlet by reciprocating between the guide groove assembly located on the side where the inlet and / or outlet are located and the guide groove assembly located on the top surface of the frame. Compared with transport trolleys using a flat-opening baffle structure, the chain gate baffle assembly does not need to flip during the opening or closing of the inlet and / or outlet, avoiding interference with shelves, goods or adjacent equipment during the flipping process.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see the appendix Figure 1 The transport trolley of this utility model includes a trolley body 100, a trolley frame 200, and a chain gate baffle assembly 300.

[0039] Please see below. Figure 1 , Figure 1 The diagram illustrates the structural relationship between the vehicle body 100, the frame body 200, and the chain gate baffle assembly 300 in this embodiment of the present invention. Specifically, the frame body 200 is mounted on the vehicle body 100, and the side of the frame body 200 is provided with a feed inlet 201 and / or a discharge outlet 202. A guide groove assembly 210 is provided on the side where the feed inlet 201 and / or the discharge outlet 202 is located and extends to the top surface of the frame body 200. The chain gate baffle assembly 300 is slidably connected to the guide groove assembly 210 to open or close the feed inlet 201 and / or the discharge outlet 202.

[0040] In this embodiment, the side of the frame body 200 is provided with a feed inlet 201 and / or a discharge outlet 202. A guide groove assembly 210 is disposed on the side of the feed inlet 201 and / or the discharge outlet 202 and extends to the top surface of the frame body 200. The chain gate baffle assembly 300 is slidably connected to the guide groove assembly 210, thereby opening or closing the feed inlet 201 and / or the discharge outlet 202. Specifically, when the chain gate baffle assembly 300 is located in the guide groove assembly 210 on the side where the feed inlet 201 and / or the discharge outlet 202 is located, the feed inlet 201 and / or the discharge outlet 202 is in a closed state. When the chain gate baffle assembly 300 is located in the guide groove assembly 210 on the top surface of the frame body 200, the feed inlet 201 and / or the discharge outlet 202 is in an open state.

[0041] When the transport trolley performs a feeding action, the control chain gate baffle assembly 300 slides from the guide groove assembly 210 on the side where the feed port 201 and / or discharge port 202 are located to the guide groove assembly 210 on the top surface of the frame body 200, thus opening the feed port 201 and / or discharge port 202 to facilitate feeding. After feeding is completed, the control chain gate baffle assembly 300 slides from the guide groove assembly 210 on the top surface of the frame body 200 to the guide groove assembly 210 on the side where the feed port 201 and / or discharge port 202 are located, thus covering the feed port 201 and / or discharge port 202 to close them. This prevents goods from falling from the feed port 201 and / or discharge port 202 during transport.

[0042] It is understood that the chain gate baffle assembly 300 slides back and forth between the guide groove assembly 210 located on the side where the inlet 201 and / or outlet 202 are located and the guide groove assembly 210 located on the top surface of the frame body 200. In this way, the inlet 201 and / or outlet 202 can be opened or closed. During the process of opening or closing the inlet 201 and / or outlet 202, the chain gate baffle assembly 300 does not need to be flipped, which is more suitable for cargo handling in dense storage environments.

[0043] In the aforementioned transport trolley, the guide groove assembly 210 is located on the side where the inlet 201 and / or outlet 202 are located and extends to the top surface of the frame 200. The chain gate baffle assembly 300 is slidably connected to the guide groove assembly 210. The chain gate baffle assembly 300 opens or closes the inlet 201 and / or outlet 202 by reciprocating between the guide groove assembly 210 located on the side where the inlet 201 and / or outlet 202 are located and the guide groove assembly 210 located on the top surface of the frame 200. Compared with transport trolleys using a flat-opening baffle structure, the chain gate baffle assembly 300 does not need to flip during the opening or closing of the inlet 201 and / or outlet 202, thus avoiding interference with shelves, goods or adjacent equipment during the flipping process.

[0044] Example 2:

[0045] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the transport trolley of this utility model. Please refer to the appendix. Figure 2 ~Appendix Figure 4 .

[0046] In this regard, please combine Figure 2 and Figure 3 , Figure 2 and Figure 3 The diagram illustrates the structural relationship between the first guide groove 211 and the second guide groove 212 in an embodiment of the present invention. Specifically, the guide groove assembly 210 includes a first guide groove 211 and a second guide groove 212 respectively disposed on opposite sides of the feed inlet 201 and / or the discharge outlet 202, wherein the first guide groove 211 and the second guide groove 212 are arranged in parallel.

[0047] In this embodiment, the two opposite sides of the chain gate baffle assembly 300 are slidably connected to the first guide groove 211 and the second guide groove 212, respectively, thereby ensuring the stability of the chain gate baffle assembly 300 during the sliding process, avoiding jamming during the sliding process, and making the overall structure more reliable.

[0048] In some preferred embodiments, the feed inlet 201 is located on the first side of the frame body 200, and the discharge outlet 202 is located on the second side of the frame body 200, with the discharge outlet 202 opposite to the feed inlet 201. When the feed inlet 201 and the discharge outlet 202 are opposite to each other, there are two guide groove assemblies 210. The two guide groove assemblies 210 are respectively located on the sides where the feed inlet 201 and the discharge outlet 202 are located and extend to the top surface of the frame body 200. That is, one guide groove assembly 210 is located on the side where the feed inlet 201 is located and extends to the top surface of the frame body 200, and the other guide groove assembly 210 is located on the side where the discharge outlet 202 is located and extends to the top surface of the frame body 200. When the feed inlet 201 and the discharge outlet 202 are the same, there is one guide groove assembly 210.

[0049] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship of the rotating shaft 310, sprocket 320, chain 330, and multiple baffles 340 in this embodiment of the present invention. Specifically, the chain gate baffle assembly 300 includes a rotating shaft 310, a sprocket 320, a chain 330, and multiple baffles 340. The two ends of the rotating shaft 310 are rotatably connected to opposite sides of the feed inlet 201 and / or the discharge outlet 202, respectively. The sprocket 320 is sleeved on the rotating shaft 310. The chain 330 meshes with the sprocket 320 and is slidably connected to the first guide groove 211 and the second guide groove 212, respectively. The multiple baffles 340 are sequentially connected to the side of the chain 330 away from the sprocket 320. There are two sprockets 320, which are respectively sleeved on the opposite ends of the rotating shaft 310 and respectively abut against the opposite sides of the feed port 201 and / or the discharge port 202. There are two chains 330, with the two sprockets 320 meshing with the two sprockets 320 one-to-one, and respectively slidingly connected to the first guide groove 211 and the second guide groove 212. The opposite ends of the multiple baffles 340 are sequentially connected to the side of the two chains 330 away from the sprockets 320.

[0050] Furthermore, the chain guard assembly 300 also includes a pressure plate, which is movably sleeved on the pivot 310 and abuts against the side of the frame 200 and the sprocket 320 respectively. The pressure plate serves to elevate the sprocket 320 so that it is flush with the first guide groove 211 or the second guide groove 212, thereby allowing the chain 330 to slide more smoothly within the first guide groove 211 or the second guide groove 212.

[0051] In some preferred embodiments, please refer to Figure 4 , Figure 4The diagram illustrates the structural relationship between the drive mechanism 350 and the rotating shaft 310 in this embodiment of the present invention. Specifically, the chain gate baffle assembly 300 further includes a drive mechanism 350, which is driven and connected to the rotating shaft 310. The drive mechanism 350 drives the rotating shaft 310 to rotate, causing the chain 330 to slide, thereby causing the chain 330 to reciprocate between the guide groove assembly 210 located on the side where the feed inlet 201 and / or the discharge outlet 202 is located and the guide groove assembly 210 located on the top surface of the frame body 200, thereby realizing the opening or closing of the feed inlet 201 and / or the discharge outlet.

[0052] In some more preferred embodiments, the drive mechanism 350 includes a first synchronous pulley 351, a second synchronous pulley 352, a synchronous belt 353, and a first drive member 354. The first synchronous pulley 351 is sleeved on the shaft 310 and abuts against the side of the frame 200 opposite to the sprocket 320. The second synchronous pulley 352 is rotatably connected to the side of the frame 200. The first end of the synchronous belt 353 is movably sleeved on the first synchronous pulley 351, and the second end is movably sleeved on the second synchronous pulley 352. The first drive member 354 is driven and connected to the second synchronous pulley 352. The first drive member 354 drives the second synchronous pulley 352 to rotate, thereby driving the synchronous belt 353 to drive, which in turn causes the first synchronous pulley 351 to rotate. When the first synchronous pulley 351 rotates, it drives the shaft 310 to rotate, thereby enabling the chain 330 to slide along the guide groove assembly 210. Preferably, the first drive member 354 can be a motor.

[0053] Example 3:

[0054] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the transport trolley of this utility model. Please refer to the appendix. Figure 5 ~Appendix Figure 6 .

[0055] Please see below. Figure 5 , Figure 5 The diagram illustrates the structural relationship between the annular conveyor belt 110 and the second drive member 120 in this embodiment of the present invention. Specifically, the vehicle body 100 includes an annular conveyor belt 110 and a second drive member 120. The annular conveyor belt 110 is movably disposed at the bottom of the vehicle frame 200, and the second drive member 120 is drivenly connected to the annular conveyor belt 110.

[0056] In this embodiment, the second drive unit 120 drives the annular conveyor belt 110 to move the transport trolley and load / unload materials. Specifically, when the transport trolley reaches the preset loading position, the feed inlet 201 opens, and an external device places goods at the feed inlet 201. The annular conveyor belt 110 then drives the conveyor belt to allow the goods to enter the frame 200. When the transport trolley reaches the preset unloading position, the discharge outlet 202 opens, and the annular conveyor belt 110 then drives the conveyor belt to allow the goods to exit from the frame 200, thus realizing loading, transporting, and unloading.

[0057] In some preferred embodiments, please refer to Figure 6 , Figure 6 The diagram illustrates the structural relationship between the plate body 341 and the scraper 342 in this embodiment of the present invention. Specifically, the baffle 340 includes a plate body 341 and a scraper 342. The scraper 342 is connected to the bottom of the plate body 341 so that when the plate body 341 approaches the annular conveyor belt 110, the scraper 342 sweeps the annular conveyor belt 110. When the chain gate baffle assembly 300 closes the inlet 201 and / or the outlet 202, the annular conveyor belt 110 continuously rotates during the movement of the transport trolley, causing the annular conveyor belt 110 to continuously rub against the scraper 342. In this way, the scraper 342 can sweep the annular conveyor belt 110, thereby preventing dust accumulation.

[0058] In some preferred embodiments, the top of the plate body 341 is provided with a clearance channel 3411 to avoid scrapers 342 of adjacent plate bodies 341. Multiple baffles 340 are sequentially connected to the chain 330, and the scraper 342 of one of the baffles 340 is located within the clearance channel 3411 of the adjacent plate body 341, so that the multiple baffles 340 are flush with each other, thereby making the overall structure more compact.

[0059] In some more preferred embodiments, please refer to Figure 5 , Figure 5 The diagram illustrates the structural relationship between the support frame 400 and the annular conveyor belt 110 in this embodiment of the invention. Specifically, the transport trolley also includes a support frame 400, which is connected to opposite sides of the bottom side of the trolley frame 200. The support frame 400 is located inside the annular conveyor belt 110, and its top surface abuts against the bottom surface of the annular conveyor belt 110. This ensures the flatness of the upper surface of the annular conveyor belt 110, making loading and unloading more stable and smooth.

[0060] The present invention relates to a transport trolley, wherein a guide groove assembly 210 is located on the side of the feed inlet 201 and / or the discharge outlet 202 and extends to the top surface of the frame 200. A chain gate baffle assembly 300 is slidably connected to the guide groove assembly 210. The chain gate baffle assembly 300 opens or closes the feed inlet 201 and / or the discharge outlet 202 by reciprocating between the guide groove assembly 210 located on the side of the feed inlet 201 and / or the discharge outlet 202 and the guide groove assembly 210 located on the top surface of the frame 200. Compared with a transport trolley using a flat-opening baffle structure, the chain gate baffle assembly 300 does not need to flip during the opening or closing of the feed inlet 201 and / or the discharge outlet 202, thus avoiding interference with shelves, goods or adjacent equipment during the flipping process.
